EXAMPLE: Car
The goal of a car is to move or go forward (or backward). To use the Universal
System Model to describe this function would be as follows:
1.
Input - step on the gas, the car takes in gas
2.
Process - the cylinders burn the fuel which makes the wheels turn
(intake/compression/combustion/exhaust)
3.
Output - the car moves forward (or backward)
4.
Feedback - the speedometer shows the speed at which the car is
moving

EXAMPLE: Blender
The goal of a blender is to produce a mixture - usually a drink or smoothie. To
use the Universal System Model to describe this function would be as follows:
